Protect GA Instances from DDoS Attacks with Anti-DDoS - Global Accelerator - Alibaba Cloud - Global Accelerator

Invokes the AttachDdosToAccelerator operation to attach an Anti-DDoS Pro or Anti-DDoS Premium instance to a Global Accelerator (GA) instance to protect your application from large-scale DDoS attacks and ensure service stability and availability.

Operation description

When you invoke this operation, take note of the following items:

The AttachDdosToAccelerator operation is asynchronous. After you send a request, the system returns a request ID, but the Anti-DDoS Pro or Anti-DDoS Premium instance is not yet associated with the Global Accelerator (GA) instance. The associate task continues to run in the background. You can invoke DescribeAccelerator or ListAccelerators to query the status of the GA instance:
- If the GA instance is in the configuring state, the Anti-DDoS Pro or Anti-DDoS Premium instance is being associated with the GA instance. In this state, you can only perform query operations.
- If the GA instance is in the active state, the Anti-DDoS Pro or Anti-DDoS Premium instance is associated with the GA instance.
The AttachDdosToAccelerator operation does not support concurrent requests to associate Anti-DDoS Pro or Anti-DDoS Premium instances with the same GA instance.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
AcceleratorId	string	Yes	The ID of the GA instance to which you want to attach the Anti-DDoS Pro or Anti-DDoS Premium instance.	ga-bp1odcab8tmno0hdq****
DdosId `deprecated`	string	No	The ID of the Anti-DDoS Pro or Anti-DDoS Premium instance to attach to the GA instance.	ddoscoo-cn-zz11vq7j****
DdosRegionId `deprecated`	string	No	The region where the Anti-DDoS Pro or Anti-DDoS Premium instance is deployed. Valid values: cn-hangzhou: the Chinese mainland. ap-southeast-1: outside the Chinese mainland.	cn-hangzhou
RegionId	string	No	The region ID of the GA instance. Set the value to cn-hangzhou.	cn-hangzhou
DdosConfigList	array<object>	No	The list of Anti-DDoS Pro or Anti-DDoS Premium instances to associate with the GA instance.
	object	No	The list of Anti-DDoS Pro or Anti-DDoS Premium instances to associate with the GA instance.
DdosRegionId	string	No	The region where the Anti-DDoS Pro or Anti-DDoS Premium instance is deployed. Valid values: cn-hangzhou: the Chinese mainland. ap-southeast-1: outside the Chinese mainland.	cn-hangzhou
DdosId	string	No	The ID of the Anti-DDoS Pro or Anti-DDoS Premium instance attached to the GA instance.	ddoscoo-cn-zz11vq7j****
DryRun	boolean	No	Specifies whether to perform a dry run. Valid values: true: performs a dry run without actually binding the instances. The system checks the required parameters, request syntax, and business constraints. If the check fails, the corresponding error is returned. If the check succeeds, an HTTP 2xx status code is returned. false (default): sends the request. After the request passes the check, an HTTP 2xx status code is returned and the operation is performed.	true
